Uploading an Event

I am running the latest update 6.9.5 and have been encountering problems when i upload an event. The error shows that there was a problem to connect with ebay server. However if i reduce the volume of the uploaded items it works. There is no problme with internet connections however since the update everything is running very slow.

I also recieved a 10007 inrenal error from GrageSAle.

Any help or updates are appreciated.
